FLUID-MEASURING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 417,563, dated December 17, 1889.

Application filed November 21, 1888. Serial No.291,518. (No model.) Patented in Germany October 80, 1888, No. 47,783 in England November 7, 1888, No. 16,151, and in Austria-Hungary February 8, 1889, No. 45,158 and No. 1,044.

To all whom t may concern.-

Be it known that I, PAUL KAULFUSS, manufacturer, a subject of the Emperor of Germany, residing at Penig, in Germany, have invented certain new and useful Improvements in Fluid-Measuring Apparatus, (the same having been patented in England, No. 16,151, dated November 7, 1888; in Germany, No. 47,783, dated October 80, 1888, and in Austria -Hungary, No. 45,158 and No. 1,044, dated February 8, 1889,) of which the following is a specification.

lar view with open valve.

The present invention relates to au apparatus by means of which iiuids can be drawn from barrels or other vessels in predetermined quantities, the apparatus closing automatically when the desired quantity has passed.

In the accompanying drawings, Figure 1 represents a vertical section of the apparatus with closed valves. Fig. 2 represents a simi- Fig. 3 represents a plan, the graduated disk being removed. Figui. represents a front view, partly in section, the section being on line II, Fig. 2. Fig.

j 5 represents a section of the measuring-valve and the measuring-vessels on line II II .of Fig.v 2. Fig. 6 represents a plan ofthe graduated disk.

The invention consists, essentially, in the employment of two measuring-vessels M, ca-

pableqof holding a certain quantity of fluid -inlet-opening E, and two outlet-openings A,

which are separated from the inlet by a partition in the said conical tube. Each of the measuring-vessels M will register or communicate with the inlet E when it is empty and with one of the outlets A when it is filled. To fill the vessels M, the valve V must be opened.

The oscillating movement of the vessels M with the sleeve Il for the simultaneous filling and emptying the vessels is automatic. The vessel M, which at the time is upright, and with the whole of the oscillating mechanism, is held in position by one of two pivoted catchest, engaging with a pin z of the vessel M. lVhen the vessel is perfectly filled, the fluid contained therein lifts the air-valve L, which closes, and by means of its spindle Z lifts the beforementioned catch k, and disengages this from the pin z, so that the vessel M, weighted by the iiuid it contains, falls from the upright into an inclined position. This movement is limited by one of vthe arms Q, one of which is fixed to each vessel, coming in contact with a rib R on the rigid body of the apparatus, and the spiral spring F serves to decrease the force of the fall and to take up all jerks, said spring for this purpose being connected to a stationary central stud or projection F2 on the frame at one end, and to the upper end of the guidearms C on the chambers. Thus when said guide-arms move to either side the spring is drawn out and exerts its force to stop the movement of the chambers, as just mentioned. Another spiral spring f, Fig. 1, is interposed between the sleeve H and a flange ofthe outlet-tube O, screwed on the conical tube K, and tends to press the sleeve II farther up on the tube K, so that the sleeve Il always lits closely on the said tube.

The number of the oscillations of the vessels M depends upon the quantity of the fluid to be withdrawn. During one reciprocating movement two fillings and two emptyings will take place, so that if, for instance, each of the vessels M holds one-eighth of a quart and three quarts are to be drawn off twelve reciprocating movements will have to take place.

For the automatic closing of the valve after the passing out of the desired quantity of liquor a separate mechanism and a graduated scale are provided, the said mechanismbeing provided at its upper end with a weighted roo pawl S, engaging with a ratchet-wheel v Z. From Fig. 4 it can be seen that when the vessels M oscillate to the right the pawl S will move the ratchet-Wheel Z to the left for the space of one tooth, while when the vessels oscillate to the left the pawl will merely be moved over one tooth to the right. Each tooth, therefore, represents one reciprocating' movement ot' the vessels M, and it follows therefrom that in starting the apparatus the vessel at the left side must be in the upright position. Each movement of the ratchetwheel Z moves the indicator Y over the graduated scale to the extent of one deg'ree until the indicator arrives at the zero of the scale, when the valve willV be automatically closed.

The indicator Y is fastened to a handle U, which is attached to the disk R', carrying the ratchet-Wheel Z and revolving within the casing G. By means of this handle the ratchet-wheel can be turned after the pawl S has beenl disengaged by depressing the small arm d connected with it. Above and concentric with the revolving' disk R is mounted on short nprights t the circular graduated scale T, over which passes the indicator Y. It it is desired, for instance, to draw off four quarts, the indicator is placed over 4 of the scale.

As described above, with each reciprocating movement of the vessels M the disk R with the indicator Y, is moved to the left for the space of one tooth until the indicator reaches the zero on the scale, when the valve will be closed and the apparatus stopped automatically, as will now be explained. l It desired, the circular scale may be replaced by a straight scale by suitably modifying the mechanism.

To start the apparatus, the indicator is adj usted on the scale according to the quantity desired to be drawn off, and the valve V is then opened by depressing the button NV, as indicated in Fig'. 2. This valve, which in its normal position is maintained closed byl means of the spiral spring must be held open during the operation of the apparatus. To this end the valve-spindle is provided with a collar Y, having a flange l), on which bears one projection or nose of a pivoted nut or tumbler n. lVhen the valve-spindle is being depressed, the flang'e b turns the tumbler n by means of the small arm a, iixed to the said tumbler, and the end of the pivoted lever h, held depressed by weight' g, secured to its pivot, as shown in Figs. 3 and et, will engage with another projection or nose of the tumbler n, thus keeping the valve-spindle depressed and the valve open by the depressed nose of the tumbler bearing against the top of the flange h of the valve-spindle. rlhe handle U is further provided with a beveled or inclined projection B, which rides up on the free end of the pivoted lever 71, and depresses' this at the moment when the indicator Y arrives at the zero of the scale, thereby releasing' the weighted end oi the lever h and unlocking the tumbler n, when the valve V will be instantly closed under the influence of the spiral spring By means of its flange c the apparatus can be easily attached to the vessel from which the fluid is to be drawn off, or, if desired, it can be secured to a tube leading out from such vessel. A ball t, introduced into the tube of the apparatus, serves to regulate the pressure and passage of the fluid. Each of `the measuring-vessels M is moreover provided with a short tube or socket having a screw cap or a plug e screwed onto it, by means of which the capacity of the vessels may be corrected and adjusted.

l.
